Notes. MACC(g,r,d) mode parameters for spectroscopy and photometry in the ROS. Here, g is the number of groups in the slope fit, r the number of reads per group, and d the number of drops after each but the last group. Both grisms use the same MACC settings, as do all three photometry bands. For both MACC modes the integration time t_int (effective time accumulating light; the time relevant for science) and exposure time t_exp (total duration of frame including one reset frame before start of charge integration; the time relevant for exposure planning) are given, using the frame duration of 1.45408 s.
